Abstract

The purpose of this study was to develop an analysis program for table tennis competitions. This analysis program for table tennis competitions was developed based on Lee's(2007). To analyze table tennis game contents, photographing, tape and digital data were used. The game contents were divided into two parts, the first analysis and the second analysis. In the first part only service, receive and gain condition were analyzed to provide real-time feedback of competition. Specific skills and offense courses were analyzed in the second part. The results were as followed. Viewing had sub-categories which were composed of offense skill, score ration and distribution, area and offense and receive course. Each score and error point were able to be simulated in the movies from serve and score. Also, a Re-paly button to create the section of movie was made. The whole event results were presented in game results, set scores and error points. The specific results of the event were presented in point condition by skill, offense area by skill, and offense area by receive area. Offense skill and point and error condition and error were presented in serve type and point/error, receive type and point/error, third ball or over point/error. Offense area by skill was presented in offense area by serve point skill, offense area by receive point skill, and third ball or over point/error. Offense area by receive area was presented in offense area by receive point area, offense area by receive area in point of third ball or over. These results are able to be converted in text file and be export. Also, the analysis program video can look up movies and game analysis results factor by file search function. This program was practically used to analyze main rival players for the 2008 Olympic Games, and updated for optimization and stabilization to apply it for the practice.
